Short summary
Soils are complex systems storing large quantities of carbon in the form of organic matter. Understanding how climatic drivers such as temperature and moisture influence the decomposition and thus the turnover of this carbon is crucial for predicting feedbacks between climate and soils. This study aims at improving our mechanistic understanding of how these factors interact to drive decomposition and thus modify the capacity of soils to emit or capture atmospheric CO2.
